/Engine/Source/Editor/BlueprintGraph/Public/BlueprintNodeTemplateCache.h
Serves as a centralized data-store for allUBlueprintNodeSpawnernode- templates. Implemented this way (rather than internal toUBlueprintNodeSpawner) since node-templates require a UEdGraph/UBlueprint outer chain. Instead of instantiating a bunch of graphs/blueprints perUBlueprintNodeSpawner, we'd rather have a small centralized set here.
